First off I don't understand you people saying that Mw2 is just like a mod. Uhh, its got a completely new story. Halo 3 didn't vary much from halo 2 in terms of game play.
; Point is, they're two different games. I'm more towards Mw2 though. And even if you personally disagree that MW1 had a great storyline and great gameplay, well then you can tell that to the mass fans following it, and the critics that gave it a high score. And if you want to complain about storylines and narrow down COD4s, then you can narrow down H3s with "Aliens attack humans. Ooooh how original" And why would ModernWarfare2 change their gameplay, they already have it nearly perfected, so not much to change.
Just like, as stated, h2 and h3s similarity in gameplay. Anyways, chill out a bit ImaGonnaGetyou, no ones being negative towards you, that doesn't mean you have to be negative to them, just because you're not insulting them directly or calling them names, doesn't mean sarcasm is any better.
Point is, both games are going to be great, and I'm going to be getting them both, but if I had a choice to get one first, it'd be Modern Warfare 2.
But jeesh, calm down.
